@Bo, I know that you are a very good and careful media quality tester since I have seen your quality tests in the media forum (when we discussed about that in the Gigarec at less the 1x thread), so if you are saying that the two methods yielded different results, I believe it.
I have read several other reports on the net saying that it is not clear in which way Varirec can effectively improve audio quality, and this is the reason why I have never used it...
To answer your last question:
well, my (wrong) idea was simply the following: "enabling" Varirec but leaving the value at 0 actually does nothing... ("change the offset level of the writing strategy of 0 units..."!).
Learned something new also this time.

But what's the point of enabling VariRec w its default 0 then, if you can simply write @4x ?
